Am I just stupid? I can't figure out how to set a marker in a sequence (Not an in/out marker, the colored oval kind). I can set one in a clip in the source-record monitor, but when I press the same key while in a sequence, it makes a cut at that position.
Make sure there is a locator button created under the record monitor row of buttons, or you can select it from the hamburger menu when the record monitor or timeline is active.
